But they're all chasing Johnson, who matched the record set by Laura Davies and Jimin Kang in 2005.

Johnson had a shot a 63 on the course two years ago.

"On 17, that's when I was 8 under and I was trying to beat my 63," Johnson said. "So then I started getting a little nervous because my goal was to get to 10 under, but I only got to 9. But when you shoot something that you've never shot before, nerves are going to happen."

Nomura had eight birdies in her career-low round.

"All in all, my putting was on, my shot was really good and the conditions were great," Nomura said. "So everything was perfect today."

Kim finished with seven birdies, including a 35-foot putt on 11 that she called "one of the longest putts I've made since the 90s."

Park, winless this season, had five birdies a week after missing the cut in Alabama to end her streak at 22 events.

Focusing on not letting her shoulder dip down too much, which she said caused her putts to veer to the left last week, Park drained a 15-foot birdie putt on the first hole.
